This output shows the columns in the specified table and the data type of each column. TABLE_CATALOG TABLE_SCHEMA TABLE_NAME COLUMN_NAME DATA_TYPE SELECT * FROM information_lumns WHERE table_name = 'Users' It generally allows an attacker to view data that. You can then query information_lumns to list the columns in individual tables: SQL injection is a web security vulnerability that a llows an attacker to interfere with the queries that an application makes to its database. This output indicates that there are three tables, called Products, Users, and Feedback. TABLE_CATALOG TABLE_SCHEMA TABLE_NAME TABLE_TYPE You can query information_schema.tables to list the tables in the database: Most database types (with the notable exception of Oracle) have a set of views called the information schema which provide information about the database.

The queries to determine the database version for some popular database types are as follows:įor example, you could use a UNION attack with the following input: You often need to try out different queries to find one that works, allowing you to determine both the type and version of the database software. This includes the type and version of the database software, and the contents of the database in terms of which tables and columns it contains.ĭifferent databases provide different ways of querying their version. When exploiting SQL injection vulnerabilities, it is often necessary to gather some information about the database itself. Examining the database in SQL injection attacks
